| dc.description.abstract | The tidal flood that occurred in northern Medan was due to the overflow
of sea water when the tide entered the mainland, either directly or through river
water overflowed. The land area affected by tidal flooding is getting wider and
wider, so an analysis of the potential tidal flood vulnerability is needed as an
effort to handle and prevent activity can be right on target. The potential for tidal
flood vulnerability uses 9 criteria, for that the AHP and GIS integration methods
are used in order to make rational decisions from several criteria that produce a
vulnerability map. The results obtained in the northern area of Medan city that
1,546.89 ha (16.39%) have a high to very high level of vulnerability, while
4,411.92 ha (46.83%) have a moderate level of vulnerability to tidal flooding. The
results of the vulnerability level show that 13 environments are in the very high
category of 6.16%, 44 environments are in the high category of 20.85% and 64
environments are in the medium category of 30.33%. In the mitigation strategy,
the efforts that must be made by the Government are 1. building pump houses, 2.
structuring buildings, especially in the environment adjacent to the coast, 3.
providing maps of tidal flood prone zones and vulnerability, 4. relocating the area
by building flats. | en_US |
